olson if you are in windows you can use print screen to capture any image on the screen to file and save it in paint. on most images you can right click and choose "view image" then copy the URL to that page in order to "steal" the photo's link. or right click "copy image to copy the image to your clipboard and then if you open paint and use paste it will be there.
If they block the ability to copy photos print screen still works so if you can see it you can copy it. on some keyboards it might be alt and another button with print screen or prtsc or something or it might be a separate button.
on iphones you can also copy the screen. I think you press home and the off button simultaneously it works like print screen and you'll hear the sound the camera makes and if you look in photos it will be there. if you hit home or the off button out of synch it will either log out or bring up Ms. siri.
on mac computers I dont' know , others would. usually with windows there are 10 ways to do anything and on macs there is one way that makes sense and not 10 different ways to do the same thing lol.. computer gurus like mick can often do a lot of amazing things in windows with start>run and by entering dos commands they can fly in and out of all kinds of menus the average bloke wouldn't know existed. Ive worked with lots of systenms guys and some were truly amazing and they would barely touch the mouse. they would refer to people like me as a "mouse man" - someone without in depth knowledge of all the real geeky guru commands.
